  Hi.
 If I get it right, nowadays, development of Java plugins/add-ons for
 XWiki is done through Plexus components. 
 Nope :)
 They are done through XWiki components. See
http://code.xwiki.org/xwiki/bin/view/Modules/ComponentModule
  
 Ah... would it be possible to update the docs and somehow then get rid
 of the old tutorial that mentions several times Plexus (or at least no
 longer reference it from the dev guides) ? 
Yes someone needs to do it. It's a wiki and anyone can participate and edit it. If I
get the time I'll give it a go.
  Also, I'd suggest to no longer point to Plexus
docs from the first
 sentence in 
http://code.xwiki.org/xwiki/bin/view/Modules/ComponentModule
 which are somehow misleading. 
I've just improved it a bit. It shouldn't be removed since it explains the
advantages of using components!
    Is there a way ATM to setup easily a HelloWorld
component development
 project in Eclipse, in order to be able to learn and test such component
 development ? 
 Sure it's very easy. You don't need to do anything. I do XWiki component dev in
Eclipse and IDEA. 
 
 What's IDEA ? 
 
an IDE.
  Is there a Howto ?  
What would you like to see in it? As I said there's nothing special to do.
So here's a tutorial for you:
- start your IDE
- start coding using the rules defined in
http://code.xwiki.org/xwiki/bin/view/Modules/ComponentModule
  Think about newbees ;) You're probably very much
aware of
 component-oriented development, but there are lots of folks that come
 from the LAMP world you know ;) 
There's nothing special to component-oriented development WRT your IDE. It's just
java code...
    It seems that the maven archetype is quite outdated,
and I couldn't find
 examples on what needs to be configured in such a Java+Maven project to
 make it work.
 Annotations support for instance doesn't seem trivial to activate for me
 (Java and Eclipse beginner). 
 Annotations is supported by default in eclipse since it's a java 5 feature.
  
 
 Is there some configuration required in the Eclipse project to support
 that ? 
 
No.
    Also, as the Plexus archetype on codehaus is in no
better shape (can't
 even be installed with maven), it doesn't help a lot. 
 You shouldn't use that since we're not using Plexus (we were using it several
months ago though but it was always under the hood and not exposed in any API).
 Please don't hesitate to post more specific questions if you need help. Right now the
best doc is:
 
http://code.xwiki.org/xwiki/bin/view/Modules/ComponentModule
   
 OK, thanks, I'll have a look at it again and start over my attempts to
 write a HelloWorld component. 
 
Good luck. You'll see it's extremely easy.
Out of curiosity, what kind of component are you trying to build?
Thanks

  Thanks and enjoy!

 PS: Feedback on component dev in xwiki is most welcome so that we can improve stuff even
further. 
 Thanks.
 Best regards,
